A compacted fill with a unit weight of 121 lb/ft^3 and a moisture content of 12.5% will be used for construction of a warehouse. Proctor compaction test was performed on a sample of the fill material. The test results revealed a maximum dry unit weight of 117 lb/ft^3 and an optimum moisture content of 13.0%. Compute the relative compaction based on the results of the Proctor compaction test.

A field density test has been conducted in a compacted fill that is currently under construction.The test results indicate a relative compaction of 101-103%, which made the constructionmanager believe the test must be incorrect.
